-5[-3+5(-2)-9(-6/3)^2]+4
Can someone answer this for me including every step of work
Simplify the following:
-5 (-3+5 (-2)-9 ((-6)/3)^2)+4
The gcd of -6 and 3 is 3, so (-6)/3 = (3 (-2))/(3×1) = 3/3×-2 = -2:
-5 (-3+5 (-2)-9×-2^2)+4
(-2)^2 = 4:
-5 (-3+5 (-2)-9×4)+4
5 (-2) = -10:
-5 (-3+-10-9×4)+4
-9×4 = -36:
-5 (-3-10+-36)+4
-3-10-36 = -(3+10+36):
-5-(3+10+36)+4
| 3 | 6
| 1 | 0
+ | | 3
| 4 | 9:
-5 (-49)+4
-5 (-49) = 245:
245+4
245+4 = 249:
Answer: |249
